Our lab extensively utilizes rodent and non-human primate models to study the temporal and spatial changes of DNA methylation (both 5-methylcytosine [5mC] and 5-hydroxymethylcytosine [5hmC]) throughout neurodevelopment toward neurodegeneration, and due to prenatal/early life stimulus (e.g., autism, schizophrenia, depression, anxiety, and Alzheimer’s disease). It is likely that most adult brain disorders emerge early in life but are commonly unrecognized and untreated. Despite the prevalence of these illnesses, the field lacks a clear understanding of their etiologies and pathophysiology. As a result, current treatments are not optimal, resulting in a failure to effectively treat childhood symptoms and leading to a greater functional disability because of cumulative damage. Our approach employs an interdisciplinary combination of basic and translational strategies to identify the molecular mechanisms affecting human behavior and cognition.
